46a643763d Implement fixed-window exponentiation to mitigate hyper-threading 
timing attacks.

BN_FLG_EXP_CONSTTIME requests this algorithm, and this done by default for
RSA/DSA/DH private key computations unless
RSA_FLAG_NO_EXP_CONSTTIME/DSA_FLAG_NO_EXP_CONSTTIME/
DH_FLAG_NO_EXP_CONSTTIME is set.

800e400de5 some updates for the blinding code; summary: 
- possibility of re-creation of the blinding parameters after a
  fixed number of uses (suggested by Bodo)
- calculatition of the rsa::e in case it's absent and p and q
  are present (see bug report #785)
- improve the performance when if one rsa structure is shared by
  more than a thread (see bug report #555)
- fix the problem described in bug report #827
- hide the definition ot the BN_BLINDING structure in bn_blind.c
